To provide the ability to recover deleted EBS snapshots for a specified period, creating a Recycle Bin retention rule for EBS snapshots is the appropriate solution.

Recycle Bin:

The Recycle Bin for Amazon EBS snapshots allows you to recover snapshots that were deleted within a specified retention period.

Creating a Retention Rule:

Open the Amazon Data Lifecycle Manager console.

Create a new Recycle Bin retention rule for EBS snapshots and specify the desired retention period.

Understand the Problem:

A user attempts to deploy a CloudFormation template to create an S3 bucket but the stack creation fails.

The user authenticates using Active Directory credentials.

Analyze the Requirements:

Identify permissions required for successful CloudFormation stack creation.

Evaluate the Options:

Option A: The user's IAM policy does not allow the cloudformation:CreateStack action.

Without this permission, the user cannot create CloudFormation stacks.

Option B: The user's IAM policy does not allow the cloudformation:CreateStackSet action.

StackSet is used for managing stacks across multiple accounts and regions, not relevant for a single stack creation.

Option C: The user's IAM policy does not allow the s3:CreateBucket action.

This permission is required to create an S3 bucket as part of the stack.

Option D: The user's IAM policy explicitly denies the s3:ListBucket action.

This permission is not required for bucket creation but for listing existing buckets.

Option E: The user's IAM policy explicitly denies the s3:PutObject action.

This permission is required to put objects in a bucket, not to create the bucket.

Select the Best Solution:

Option A and C: The user must have permissions for cloudformation:CreateStack and s3:CreateBucket to successfully create the stack and the S3 bucket.

IAM Policies and Permissions

Ensuring the user has the required permissions for cloudformation:CreateStack and s3:CreateBucket is crucial for successful stack creation.

The connectivity issues could be due to:

Security Group Ingress Rules:

Ensure that the security group for the RDS database has the correct ingress rules allowing traffic from the web server's security group or IP address.

Go to the RDS console, select your database instance, and check the security groups.

In the security group settings, verify that the correct port (usually 3306 for MySQL) is open for the web server's IP or security group.

Port Configuration:

Verify that the application is configured to use the correct port that matches the RDS database configuration.

Check the application configuration files to ensure the port number matches the port specified in the RDS instance.

Elastic Load Balancing provides access logs that capture detailed information about requests sent to your load balancer. Each log contains information such as the time the request was received, the client's IP address, latencies, request paths, and server responses. You can use these access logs to analyze traffic patterns and troubleshoot issues.

https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-access-logs.html

'Network Load Balancer is optimized to handle sudden and volatile traffic patterns while using a single static IP address per Availability Zone.' https://aws.amazon.com/elasticloadbalancing/network-load-balancer/

For an application that must scale to millions of requests per second and requires a single static IP address for each Availability Zone, a Network Load Balancer (NLB) is the most suitable option. NLBs are designed for high-performance, low-latency networking, and they support static IP addresses for each Availability Zone, making it ideal for volatile traffic patterns. Option D is the correct choice. AWS provides extensive documentation on NLB capabilities and configurations that suit these requirements AWS Network Load Balancer.
